FOR PRINTING-PRESSES.

i To all whom it may concern:

Be it known that WG,,BENEDIGT W. SHALL- BETTER and WILLIAM T. ABBAMS,citizens of the United States, residingat; Minneapolis, inthe county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements, in Ink-Fountains for Printing-Presses; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use thesame.

Our invention has for-its object to provide an improved. ink fountainfor printing presses; and, to this end, it consists of the novel devicesand combinations of devices hereinafter described and defined in theclaims. a a

Considerable difficulty is experienced with the ink fountains now ingeneral use when it is necessary to change the color of the ink heldtherein or in givingthe same a thor: ough cleansing. This difficulty:arises in the attempt to separate the parts of the ink fountain whichare usually thoroughly ce' mented together by ink that has workedtherebetween and dried and in theremoval of the unused ink from the inktrough. This separation and cleansing of the parts necessitates a largeamount of dirty work and requires the press to stand idle for aconsiderable length of time. To overcome this difficulty, we provide afeed roller and an ink trough which may be simultaneously andbodilylifted from the casing in which they are mounted, at which timesaid roller is held in its original position with respect to the inktrough, thereby actingas a stopper to prevent the inkfrom flowing fromthe ink trough at the time said ink trough is being removed from thecasing and carried to a receptacle provided for holding the ink.

. Our invention also providesmeans whereby the feedroller and inktroughmay be very quickly secured in a workingposition: within the casing orremoved therefrom.

In the accompanying drawings, which illustrate the invention,likecharacters indicate like parts throughout the several views. Y

Referring tofthe drawings, Figure 1 is a right side elevation of theimproved ink fountain and supporting arm, which connects the same to theframe of the printing press; Fig.2 is a plan view of the same, re-

moved from its supporting arm; Fig. 3 is a longitudinal verticalsection, taken on the irregular line 12 m of Fig. 2; Fig. 4 is a frontend elevation of the improved ink fountain, some parts being brokenaway, and some of the exposed parts being shown in section andIfi g. 5is a left side elevation of the same.

Of the parts ofthe printing press illustrated forthe purpose of showingthe improved inkfountain applied in working position, the numeral 1indicates the press frame, and the numeral 2 indicates the rotary inkplate or dial.

Referring now in detail to the improved inkfountain, the numeral 3indicates a horizontally extended rectangular casing, open at itsforward end, and hinged near its rear end for vertical swinging movementto a pair of laterally spaced, vertically projecting hinge lugs l. Thesehinge lugs 4 project through the bottomof the casin 3, engage the innervertical faces of the sides of saidjcasing 3, and thereby hold saidcasing against lateral movement. As shown, the hinge lugs 4 are integralwith a plate 5 secured to the outer end of a bracket 6 by a set screw 7.This bracket 6 is secured to the press frame 1 for longitudinaladjustments toward and from the dial. 2 by a set screw 8, adapted to bepassed through any one of a plurality of longitudinally spacedperforations, not shown, in the bracket 6.

The free orqinner end of the casing 3 is held indifferent verticaladjustments with respect to the dial 2 by a long vertically extendedthumb-screw 9, having screwvthreaded engagement with the bracket 6, andon which rests the bottom of the casin lock nut 10 is provided forholding the thumb screw 9 against rotation in the bracket 6. Obviously,by turning the thumbscrew 9 in the proper clirection,the inner end ofthe casing}; may be raised, and by turn-.

ing said screw in a reverse direction, said casing will follow the sameunder the action of gravity. l

' easing. 3, which, in turn, secures the tubular shaft 15;.in theseats13, by lever-equipped sections 11.

The outer upper end portions of the sides of the casing 3 are formedseparate from the main portion thereof to afford movable side These-sidesections; 11 are hinged to the casing 3, at their inner ends,

'for vertical swinging, movement, by rivets- 12. The lower half of apairofhorizontal axially alined bearing seats 13 is formed in the sidesof the'casing 3',and the cooperating upper half thereof is formed inthe-lower horizontal edges of the hinged sections 11.

Mounted in the open endof-the casing 3, between the sides thereof,is afeed roller 14, keyed to the intermediate portion of a tubular shaft 15,journaled, at its ends, in the, seats 13. Integrally formed on one endof this tubular shaft 15, and located on the right side of i the casing3, is) a ratchet and a swinging movement ofsaid lock links v wheel 16.1

The hinged sections '11 are locked to the 18. The hinged sections 11 arefurther locked to the casing 3 against outward lat eral movement bydepending lips 11*, formed thereon and arranged to engage the innervertical faces of the sides of said casing when said sections are turneddown. These lips 11 also perform another important function that willpresently appear. When the lock heads 17 are swung on the lock links 18into a position, indicated by dotted lines in Fig. 5, thehinged'secti'ons 11 may be raised as indicated by dotted lines in Fig..5, thereby permittingjthe shaft 15 and attached feed roller 14 to beremoved together from the casing This removal of thefeed roller 14 andits shaft 15, simul taneously and as an entirety, from the casing, 3,"is highly important, as will presently appear.

Intermittent rotary movement is imparted to the feed roller 14, in thedirection of the arrow marked-on Fig. 1, by an oscillatory arm22,vhaving a laterally projecting.

shaft, 23, journaled in and extending completely through the tubularshaft 15; Formed on the outer projecting end: of the shaft 23, is} an.annular groove 24, into which one'of the straps of thelock links 18enters to detachably secure said, shaft.

against removal from the shaft 15. Obviously, by manipulating theleversof thelock, head 17, the hinged sections 11 and the J shaft 23 maybe simultaneously locked in operative positions oryreleased ,therefrom.-Pivotally mounted on the arm 22,- above; its

shaft 23, is a lock dog 25;, which cohperates with, the ratchet wheel-16 to ,rot ate the feed roller 14 inthe direction of said arrow whenthe freeend ofxthe 'arm 221s pulled down, butwillslip o'versaid ratchetwheel when. said. arm moves up. The outer, "01

closelyengage the same." The sides ofthe' ink trough 29 extendsubstantially to: the

axis of the I feed roller 14 and they are notched at their intermediateend portions to afford a clearance for'thesh'aftl5. By

spaced a considerable distance from the H 4 sides of the casing 3,thereby preventing any of the ink from working into the bearings of theshafts 15 and 23.v It will! alsobe noted thatthe ends of the feedroller14'are.

formed with annularchannelsSO,whichfur ther prevent the ink from workingfrom the ink trough into said bearings. i The. :li'ps 11 ,-previouslyreferred'to, engage thesidesof the ink trough '29 and hold the sameengagement with the ends of the fe d roller 14. I a.

The outer end of theink'trough 29 rests directly on the upper edge ofthe outer end of the casing 3 and is supported thereby.

The ink trough 29 is held against endwise movement in the. casing 3 by adepending bifurcated'spring 31, formed on the outer end thereof; Thisspring 31 bears against the outer vertical face of the end of the casing3,.and the prongsthereof embracea thumb-screw 32, having screw-threaded'en- 1 r 125 gagement" with said. casing, arranged, to clamp said sprngonto sa1d cas ng: :This

spring 31'tendsto move the lower "end of the bottom of the inktrough" 29axially away fromthe feed roller 14. Secured *to' the mk trough '29,just above the springi3l,

100 reference to Figs. 2 and 4, itwill benoted that the sides of theink'trough 29' are;

contact therewith by the spring 31.

menace is a finger piece 33, bywhich said trough may be lifted to andfrom the casing 3.

As shown, an adjusting wedge 34 is pro vided for moving the lower end ofthe ink trough 29 toward the axis of the feed roller 14, against thetension of the spring 31. This wedge 34 is mounted to slide directly onthe bottom of the casing-3, and is held for straight line movement by apair, of screws 35, which work in parallel slots 36 formed in the bottomof saidcasing. The ink trough 29 rests directly on; the upper face ofthe wedge 34: and is yieldingly held in Endwise sliding movement isimparted to the wedge 3-11: by a long horizontally extended thumb-screw37, passed througha perforation in the outer end of the casing 3, andhaving screw-threaded engagement with said wedge. A collar 38, pinned tothe thumb-screw 37, holds the same against endwise movement in thecasing 3, but permits free rotary movement thereof. Obviously, byadjusting the wedge 34, the ink trough 29 may be properly positionedwith respect to the feed roller 14 to cause just the right amount of inkto pass from the said trough to the feed roller.

By adjusting the bracket 6 on the press frame 1, and the casing 3 on thebracket ,6, the feed roller 14 may be positioned so that the form rollerwill properly engage the same.

From the foregoing description it is evident that by opening the hingedsections 11. in a mannerpreviously described, and loosening the setscrew 32 to release the spring 31 from the casing 3, the feed roller- 14and ink trough 29 may be bodily and sin'iulta-neously removed from thecasing 3. a At the time the feed roller 14 and ink trough 29 are removedfromthe casing 3, said roller is held in its original position with saidink trough, thereby actin as a stopper to close the delivery end of sa1dtrough and prevent the flow of ink therefrom. After the feed roller ltandink trough 29 are removed from the casing 3, the ink in said troughmay be emptied into a receptacle, and said trough then placed in a lyebath for the purpose of cleaning the same. The ink on the feed roller 14may be readily removed by the use of benzina When the feed roller 14properly cleaned, the same, together with another ink trough, containinga fresh sup-i ply of ink, maybe placed in the casing 3 and the pressagain started with only a short delay from the time the first inktrough: was removed therefrom. By thus providing eachpress with two ormore ink troughs, different colored inks may be used on the press, withvery little delay in making the change, and with very little work, andno dirt.

-Theabove described device, while extremely simple andof comparativelysmall cost to manufacture, is thought to be highly etlicient for thepurpose had in view.
